Thinkstock Images/Getty Images(TORONTO) -- The main stage at the Ottowa Bluesfest music festival collapsed Sunday just 20 minutes into a performance by rock group Cheap Trick, leaving attendees stunned and at least three people injured.

"Everyone is okay and we are so lucky to be alive and hope that all the fans are okay too," the band wrote on their Facebook page.

Toronto's Globe and Mail reports a piece of the stage pierced the abdomen of a 46-year-old man, whose injuries also included a fractured pelvis and a fractured leg. He's in an Ottawa hospital in serious condition. Two others were taken to the hospital with a chest injury and a neck injury, respectively.

Prior to the event, winds were forecast to exceed 50 miles per hour. Due to the weather conditions, a scheduled performance by headliner Death Cab for Cutie was also canceled.
